CALL CONTROL SYSTEM

PURPOSE:To reduce a processing amount in an exchange when the connection and release of a call with a same connection opposite party are repeatedly executed. CONSTITUTION:A statistical information integrating device 6 monitors the generation of the call through call control interface control parts 1 and a switch control device 3 so as to give indication to the switch control device 3 to leave the internal connection of a switch 2 even if the call executes completion in connection with a high generation frequency. The internal connection of the switch 2 is held in an internal connection storing device 4. When the call requesting same connection to a place where the internal connection of the switch 2 is left is generated again, the statistical information integrating device 6 requests the revival of internal connection to the switch control device 3. The switch control device 3 completes call connection based on the revival request.
